[background technique]
Existing fan frame is generally the one design, as No. the 578947th, TaiWan, China patent announcement, this fan frame comprises a seat board, place newel, the frame on the seat board and seat board is connected to some connecting plates of frame, wherein seat board, newel, frame and connecting plate are formed in one, and its material is the same.So, there are many drawbacks in this kind design: 1. in product development, often needing wherein, a part has particular performances, and other parts are not had this requirement, as partly needing intensity higher to newel, and low to the frame requirement of strength, and must use high-intensity material in order to reach the whole fan frame part of requirement of strength, cause waste; 2. when certain part of fan frame was damaged, whole fan frame promptly needed to change, and recuperability is poor, also can cause waste simultaneously.
Therefore in order to save cost, improve recuperability and the housing and the asynchronous usability of newel material of fan frame, need a kind of new assembled fan frame of design.
[summary of the invention]
The purpose of this utility model is to provide a kind of low cost, easily assembling, dismounting, recovery and the good assembled fan frame of interchangeability.
The purpose of this utility model is achieved through the following technical solutions: a kind of assembled fan frame, the bearing support that it comprises a framework, is connected in the fixing frame of framework and is connected in fixing frame, framework and fixing frame be connected and fixing frame and bearing support be connected at least that one of them is removably to connect.
Compared with prior art, the utility model assembled fan frame is not one-body molded but this assembled fan frame is divided into three parts, so design, framework, fixing frame and bearing support each several part are independent, assembling that can be flexible and dismounting, thereby the material of framework, fixing frame and bearing support can be different, and recuperability is good.
[embodiment]
Please refer to Figure 1 and Figure 2, the utility model assembled fan frame 1 comprises a square framework 10, removably is mounted on the fixing frame 20 on the framework 10 and be removably installed in bearing support 30 on the fixing frame 20.
Square framework 10 is made by plastic material, framework 10 is provided with a hollow base 12 and reaches by upwardly extending four sidewalls 14 in base 12 edges, base is provided with hole clipping 122 that runs through base 12 and the depression 123 (with reference to Fig. 3) that does not run through base 12 for 12 4 jiaos, and this depression 123 communicates with this hole clipping 122.Base 12 is provided with a pair of retaining wall 124 between hole clipping 122 and depression 123, with reference to figure 3.
Fixing frame 20 comprises a chassis 24 and is linked to around the chassis 24 and orthogonal four ribs 22.Chassis 24 central authorities are provided with a circular hole 244, chassis 24 is provided with upper surface 240 and lower surface 242, run through chassis 24 upper and lower surperficial 240,242 and be provided with two breach 246,24 lower surfaces 242 are provided with the alcove 248 that connects mutually with breach 246 in the chassis, be provided with a raceway groove 230 in these alcove 248 surfaces, with reference to figure 4, this raceway groove 230 does not run through the upper surface 240 on chassis 24, rib 22 ends are provided with holding section 224, and this holding section 224 comprises fixture block 226 and a pair of card ear 228 that with hole clipping 122 cooperate corresponding with the depression 123 of base 12.This is to card ear 228 resiliently deformable in opposite directions when being squeezed.Holding section 224 and the hole clipping 122 and 123 common formation first bayonet units that cave in are to be removably installed in fixing frame 20 on the framework 10.
Bearing support 30 can select to be different from the material of framework 10 according to the design strength demand, as metal.This bearing support 30 comprises a pedestal 32 and the newel 320 that extends from these pedestal 32 upper surfaces, pedestal 32 lower surfaces are provided with two projections 324, lacking of these projections 324 and said fixing frame 20 chassis 24 is 246 corresponding, projection 324 towards the surperficial end of pedestal 32 be provided with one with above-mentioned raceway groove 230 corresponding raised lines 232, with reference to figure 5, this alcove 248 and projection 324 constitute second bayonet unit, so that bearing support 30 is removably installed on the fixing frame 20.
During assembling, at first with the fixture block 226 of fixing frame 20 and depression 123 and the hole clipping 122 on card ear 228 aligning frameworks 10 bases 12, push this fixing frame 20 towards base 12, card ear 228 ends are squeezed and are out of shape in opposite directions and slip in the hole clipping 122, when passing this hole clipping 122, card ear 228 recovers undeformed state, its end engages with base 12 another surfaces, simultaneously fixture block 226 be contained in the depression 123 of base 12 and with the retaining wall 124 of base 12 against, thereby this fixing frame 20 utilizes this first bayonet unit to be fixed on this framework 10; Then bearing support 30 is placed on the chassis 24 of fixing frame 20, make two projections, 324 correspondences of bearing support 30 pass the breach 246 on chassis 24, again with bearing support 30 towards the alcove adjacent 248 rotations with breach 246, so that projection 324 is contained in alcove 248, till the raceway groove 230 of the raised line 232 of projection 324 and alcove 248 fastens.Be appreciated that ground, in the installation process, bearing support 30 can be installed on earlier on the chassis 24 of fixing frame 20, and then the fixing frame 20 that will install bearing support 30 is installed on the framework 10.The utility model assembling finishing back is shown in Fig. 6 and 7.
If some part of this assembled fan frame 1 need be changed or keep in repair, during dismounting, the pedestal 32 of bearing support 30 is rotated in the alcove 248 on fixing frame 20 chassis 24, thereby the raised line 232 of pedestal 32 bottom surface upper protruding blocks 324 makes raised line 232 and raceway groove 230 break away from buckle by resiliently deformable, and then two projections 324 of bearing support 30 pedestals 32 are rotated to breach 246 places of fixing frame 20 pedestals 32, thereby this bearing support 30 is taken out from assembled fan frame 1; Make card ear 228 generation resiliently deformables and break away from buckles by card ear 228 ends of pushing fixing frame 20 again, will take out its hole clipping 122 from framework 10 bases 12 then, so fixing frame 20 and framework 10 are separated from each other with hole clipping 122.Be appreciated that ground, in the unloading process, the fixing frame 20 that has bearing support 30 can disassemble from framework 10 earlier, and then the chassis 24 of bearing support 30 from fixing frame 20 disassembled.
In aforementioned introduction, the hole clipping 122 of this first bayonet unit and caving in 123 is located on the framework 10, and holding section 224 is located on the fixing frame 20, is appreciated that ground, the hole clipping 122 of first bayonet unit and caving in 123 can be arranged on the fixing frame 20, and the holding section is arranged on the framework 10.Equally, the alcove 248 of second bayonet unit can be arranged on the bearing support 30, and projection 324 is arranged on the fixing frame 20.
Framework 10 of the present utility model, fixing frame 20 and bearing support 30 all are elements independently, can design separately, adopt different materials.Be appreciated that ground, the utility model also can allow fixing frame 20 and bearing support 30 one-body molded, and fixing frame 20 and bearing support 30 Whole-dismountables be installed on the framework 10, can also allow fixing frame 20 and framework 10 one-body molded, and the bearing support 30 of design is removably installed on fixing frame 20 and the framework 10 separately.
In addition; framework 10 of the present utility model, fixing frame 20 and bearing support 30 interconnective modes are detachable connection; but be not limited to specification and the graphic middle structure that discloses; also can be other modes; as be threaded, mode such as bonding, so long as fixing frame 20 and framework 10, bearing support 30 and fixing frame 20 removably structure and mode all in the utility model protection domain.
